DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

The discovery of DNA structure by James Watson and Francis Crick in the year 1953 is one of the most revolutionary scientific discoveries to date. However, the research leading to the discovery of ...

B-DNA is the most common form of DNA and has a right-handed double helix structure. A-DNA forms in a shorter, right-handed double helix. The function of this form is to protect DNA.

Nucleotides: DNA is composed of four types of nucleotide building blocks – adenine (A), thymine (T), guanine (G), and cytosine (C).Each nucleotide consists of a phosphate group, a sugar group ...

DNA is a biological molecule that contains the instructions an organism needs to function, develop, and reproduce. It is present in all forms of life on earth and contains each organism’s ...

Structure: DNA consists of two strands, arranged in a double helix. These strands are made up of subunits called nucleotides. Each nucleotide contains a phosphate, a 5-carbon sugar molecule and a ...

In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to ...

The structure of DNA was discovered by scientists James Watson and Francis Crick along with Maurice Wilkins. They were awarded the Nobel prize in 1962 for their discovery of DNA structure.
